Cataloguing plugins (value builders)
====================================

With value builders you can enhance your cataloguing with additional features like validation, link creation, auto-generation of numbers etc.

A value builder is a perl script that, within a MARC framework, is linked to a certain subfield in biblios, authorities or items. Cataloguing plugins are not to be confused with :ref:`plugins.rst <Koha plugins>`

Set up
-------------------------
To use a value builder in your MARC framework, navigate to Administration -> MARC bibliographic framework and then to the MARC structure of the desired framework.
Search for or browse to a field, and choose Edit subfields from its Actions menu. Go to the subfield's tab, and choose the relevant entry from the drop down list at "plugin".

Example
--------------------------

Adding the call number browser to the items editor:

#. In your MARC framework, go to field 952 and edit subfield o.
#. Choose cn_browser.pl from the "plugin"-List.
#. Save your changes.
